N-Acetyl L-Tyrosine is a brain supplement that has quickly grown in popularity.

The amino acid L-Tyrosine is critical for a number of different bodily functions such as cognitive processes, building muscles, and cell growth and recovery.

Taking N-Acetyl L-Tyrosine may support peak performance from both your brain and body by improving neural communication and helping you better handle stress.

It is one of the cognitive enhancement supplements that may promote better balance of the neurotransmitter levels in your brain. For this reason, almost anyone may benefit from using N-Acetyl L-Tyrosine supplements and it is a common addition to nootropic stacks with Racetams and some of the more potent brain boosters out there.

Before you decide to buy some NALT, read on to learn about what it is and how it acts in the body, more about its benefits, the risk of side effects, and the best practices for using it.

N-Acetyl L-Tyrosine, or NALT for short, is considered to be a modified formulation of the non-essential amino acid, L-Tyrosine.

L-Tyrosine is an amino acid that the body is capable of producing internally, but supplementation is often necessary to optimize cognitive function.

NALT is modified from normal Tyrosine because it contains the addition of acetic acid. This is believed to help increase the compound’s bioavailability so that it is better absorbed directly into the bloodstream, however research on this is limited.

Acetic acid also has some important benefits in its own right for brain health. For these reasons, N-Acetyl L-Tyrosine is a popular form of supplemental L-Tyrosine.

Amino acids are vital to the body for a number of reasons. They help to make proteins, build up new cells, aid in the recovery and rebuilding of muscles, etc. But one of the main things which makes Tyrosine special is that it also is a precursor to the catecholamines.

Catecholamines are a group of monoamine compounds that act as hormones and neurotransmitters in the body. The main catecholamines are Dopamine, Epinephrine (Adrenaline), and Norepinephrine (Noradrenaline). These powerful neurotransmitters are associated with mood, attention, focus, and alertness.

Benefits of N-Acetyl L-Tyrosine

The way in which the NALT actually works within the body is a bit complex and still not fully understood. However, it is clear that NALT is an incredibly strong and bioavailable form of the amino acid Tyrosine.

Through an ezymatic process, Tyrosine is converted into a versatile chemical called Levodopa (L-Dopa). This then is used to make Dopamine as well as several other helpful chemicals involved in mental functioning.

One of the things that L-Dopa does is convert into Melanin. This process of conversion forces the removal of things called quinones which can cause neurotoxicity.

Additionally, Melanin is a chelating agent within the brain, accumulating and removing harmful metals like mercury and lead. The Dopamine which is not used directly for boosting your mood is also turned into Norepinephrine.

It has been hypothesized that supplementation with NALT may improve memory formation, learning capacity, and general comprehension and analytical skills. Also, many users have reported a feeling of mental energy, focus, and concentration. Others seem to have more clarity and mental fluidity.

Not only does Tyrosine play an important role in our cognitive processes and overall mood, it may actually help us handle stress better. It is known that stress can deplete levels of the catecholamine neurotransmitters.

It is believed that supplementation with L-Tyrosine may increase levels of this precursor and allow for increased catecholamine synthesis, potentially helping avoid the negative effects of stress and anxiety.

One clinical study found that in patients given Tyrosine before a cold-stress test, cold-induced reductions in cognitive performance were mitigated compared to patients given a placebo. Another study found similar results when testing memory during a cold-stress test; patients who were given Tyrosine were seen to have improved working memory compared to placebo patients.

The Natural Medicines Comprehensive database has rated L-Tyrosine as Possibly Effective for improving cognitive performance and memory under stressful conditions, and for increasing alertness following sleep deprivation. L-Tyrosine and NALT are available as dietary supplements, and the FDA has not approved either compound as a drug to prevent or treat any conditions.

Side Effects of NALT

N-Acetyl L-Tyrosine is believed to be very safe, non-toxic and well-tolerated in healthy adults. Most L-Tyrosine reviews do not mention any negative side effects or unpleasant reactions when taking this nootropic agent.

However, there have been some instances of side effects associated with it when it is taken at high dosages (above 150 mg/kg bodyweight daily). These effects may include migraine headaches, fatigue, and gastrointestinal distress such as nausea and heartburn.

It is recommended that you speak to a qualified health professional before combining N-Acetyl L-Tyrosine with any of these medications or supplements to avoid negative effects.

Dosage & Suggested Use of N-Acetyl L-Tyrosine

Proper dosage depends on many different factors incuding age, weight, sex, and the reason for taking a supplement. The following dosage recommendations are general guidelines only, and your personal dosage may be different.

As with all supplements, it is recommended that you first consult with your doctor about their recommendations for usage before you start taking N-Acetyl L-Tyrosine.

The typical dosage range of NALT is between 300 and 500 mg per day. This could be taken all at once or several times throughout the day. You may find that your body responds at even smaller dosages or you may need more, but you should not exceed 1000 mg in a single day unless directed to do so by your doctor.

You can either buy N-Acetyl L-Tyrosine supplements on their own or find it in some of the pre-formulated brain supplement products out there. L-Tyrosine is included in Onnit Lab’s Alpha Brain nootropic stack at a rate of 300 mg per serving which is 150 mg per capsule.
